ABB 3BHB90211000595 ACS2000 Medium Voltage Drive – High-Efficiency VSI Drive for Pump, Fan & Compressor Applications

Product Overview

The ABB 3BHB90211000595 is the catalog/spare reference for ABB’s ACS2000 series medium-voltage (MV) voltage-source inverter drive, positioned as ABB’s compact, air-cooled MV drive solution for the 250–2500 kW power class. As a member of the ABB ACS family, the ABB ACS2000 bridges the gap between low-voltage drives and the larger water-cooled ACS5000/ACS6000 series, targeting applications where footprint, cost, and transformerless connection matter. The ABB 3BHB90211000595 unit implements a 9-level line-to-line Voltage Source Inverter (VSI) topology built on high-voltage IGBTs, paired with a 5-level self-commutated IGBT Active Front End (AFE) that can be connected either through a two-winding isolation transformer or directly to the utility network (Direct-to-Line, DTL) without a transformer.

Within the automation hierarchy, the ABB 3BHB90211000595 (ACS2000) acts as the final power conversion stage between the MV supply and a standard cage-rotor induction motor. Its VSI architecture means the motor does not require derating or a specially filtered motor — ordinary DOL-rated induction motors are compatible, which is a key differentiator versus current-source LCI drives. Rated input voltages cover 4.16 kV, 6.0 kV, 6.6 kV and 6.9 kV at 50/60 Hz, with a typical converter efficiency of 97.5% and a controllable input power factor adjustable to unity or used to compensate reactive power elsewhere on the same bus. The drive is fully compliant with IEC 61000, IEEE 519 and GB/T 14549 harmonic standards thanks to the AFE front end.

From a positioning standpoint, the ABB ACS2000 is engineered for process industries that need MV drive performance without the footprint, complexity or capital cost of a water-cooled, multi-level system. The ABB 3BHB90200595 (the 3BHB90211000595 reference) is supplied as a complete drive assembly or as the principal drive hardware article for cabinet integration, supported by ABB DriveWindow and DriveMonitor diagnostic software, and backed by ABB’s global MV drives service network.

Main Features and Advantages

Transformerless Direct-to-Line capability:

The ABB 3BHB90211000595 ACS2000’s 5-level AFE front end can be connected directly to the MV utility without an input isolation transformer (DTL variant), significantly reducing footprint, losses and CAPEX. Where galvanic isolation is preferred, a two-winding transformer is also supported, giving engineers flexibility per site constraint.

9-level VSI output with standard-motor compatibility:

Unlike current-source LCI drives that often require a specially filtered or de-rated motor, the VSI topology of the ABB ACS2000 delivers <5% THDi motor-side harmonics, allowing plants to keep their existing DOL-rated induction motors. This protects prior CAPEX and shortens retrofit cycles.

Active Front End with near-unity power factor:

The AFE actively shapes input current, keeping input PF close to 1.0 across load range and meeting IEEE 519 / IEC 61000 harmonic limits without external filters. The PF setpoint is even adjustable so the drive can compensate reactive power for other loads on the same PCC — a subtle but valuable plant-level advantage.

Compact air-cooled footprint:

The ABB 3BHB11000595 (3BHB90211000595) is air-cooled rather than water-cooled, eliminating the chilled-water infrastructure needed by larger ACS5000/6000 units. Redundant hot-swappable cooling fans with automatic duty changeover are available, improving availability in hot climates.

Integrated protection and diagnostics:

Standard protections cover earth fault, overcurrent, short-circuit, motor overload/stall/overspeed, cabinet overtemperature, mains breaker supervision and communication watchdog. The ABB ACS2000 works natively with ABB DriveWindow and DriveMonitor for condition monitoring, fault playback and remote teleservice — critical for mines, water utilities and power stations running 24/365.

Modular serviceability:

Major assemblies (AFE section, inverter section, control cubicle, auxiliary compartment) are sectionalised, so a spare ABB 3BHB90211000595 drive or sub-assembly can be swapped with minimal downtime. ABB’s global MV spare logistics and 24/365 telephone support further reinforce uptime commitments.
